, to limit the opening of the limbs. The usual ree- Y tangular magazineI8 is provided, with two longi-Y tu-dinal grooves I92U in oppositewalls, respectively,andoarch-shaped cut outs 22 atthe lower Y edgesof-thelatter.Y 1 The groove I9Y terminates shortly before thelowerend'of the magazineV whereas thegroove 20 opens into thearch-shaped YorV branches are suitablylafiixed at the upper part date,respectively, theftwo` curved extremities of Y Y 55 Y magazineV I8 belowthe terminal point of groove Y I9 and passesV the Z shaped slots 30. `Aspring 34, wound about'a screw 35, is located below the arms @tween thejaws.

' Two arms, a left arm 28 and a righthone 29 are Y pivotedto thelimbs23, 24, respectively, shortly above the YiiexuresV thereof, Vso as ltoproject inwardly adjacent the wall of the magazine in which the grooveI9 is` provided. These arms are enlarged at their freeends and providedwith Z shaped apertures-30 in the enlarged portions (see Figs.` l2-and14). A screw 32 is secu/red'to the 28 and 29 and pressestherlatterupwardly,,whereby the inner end walls of the Ylower slotportions 3I abutvagainst the screw 32 and hold the arms 28, 29 thelimbs23, 24 and the jaws 21 against the divaricating tendency of thelimbs in a predeterminedpo'sitiornin which the lowermostrclipjcan YVenter between theY jawsj21 but Yca mot pass the same.
